Looking for suggestions for decentralized alternatives to Facebook groups, preferably based on nostr but open to other protocols as well. I've looked into #oxchat, it looks like what we want but apparently past 100 members it gets less reliable.
Needed features:
1. Joining group requires mod approval
2. Group chats aren't visible to anybody outside the group due to encryption
3. Mod ability to remove members at will
4. Ability to scale to say 250 members in a group
